Synthesis of novel white flake polyaniline

A novel polyaniline have been successfully prepared by in situ emulsion polymerization using KIO3 as an oxidant. White polyaniline was observed after 3 h the color of the polyaniline is usually black or green. This change in polyaniline color has led to an interest in its use for display devices, packaging and other applications. Scanning electron microscopy was used to characterize the morphology of polyaniline. The chemical structure of products was determined by Fourier Transform Infrared Spectroscopy (FTIR) and UV–vis spectroscopy. The results show that the type of surface active agent affects the intensive of peaks. This process leading to white flake polyaniline plate with 0.015–140 μm particle size and approximate yield of 40%.
